oil??

hi all ive got an 08 millie with ohline front forks which im bottoming out on trackdays with all adjusters as hard as they will go. i am about 19 stone!!!! the bike has done a few miles for its age so planing on changing oil but uping it a grade. anyone no wot grade of oil is standered and how...

So I'm doing my first oil change and I don't want to over fill it (like the shop that serviced it for me last time did). When I checked my manual, it said this nonsense for engine oil capacity: Oil change 225.788 in3 (3700 cm3) - oil and oil filter change 237.993 in3 (3900 cm3) Whaa?
